< cpp‎ | io‎ | basic ostringstream

std::basic_string_view<CharT, Traits> view() const noexcept; |  | (since C++20)

Obtains a std::basic_string_view over the underlying string object. Equivalent to return rdbuf()->view();.

### Parameters

(none)

### Return value

A std::basic_string_view over the underlying string object.

### Example

Run this code

    #include <iostream>
    #include <sstream>

    int main()
    {
        // input/output stream
        std::stringstream buf1;
        buf1 << 69;
        int n = 0;
        buf1 >> n;
        std::cout << "1) buf1 = [" << buf1.view() << "], n = " << n << '\n';

        // output stream in append mode
        std::ostringstream buf2("test", std::ios_base::ate);
        buf2 << '1';
        std::cout << "2) buf2 = [" << buf2.view() << "]\n";

        // input stream
        std::istringstream inbuf("-42");
        inbuf >> n;
        std::cout << "3) inbuf = [" << inbuf.view() << "], n = " << n << '\n';
    }

Output:

    1) buf1 = [69], n = 69
    2) buf2 = [test1]
    3) inbuf = [-42], n = -42
